Have itchy anus, abdominal pain and compressed stool. How to overcome this problem?

Hi XXXXXX,
Welcome to XXXXXXX forum.

With the available described symptoms, there appears to high possibility of parasitic infestations.
Stomach pain along with itching at anus suggests the diagnosis.
Other possibility could be dermatitis at anus, peptic ulcer disease.

You should consult with XXXXXXX medicine specialist/ gastroenterologist and should go for thorough check up.
You should also go for complete blood count, serum amylase & lipase, stool routine microscopy for ova, ultrasound imaging.

Meanwhile, you should also take proton pump inhibitors, albendazole and dicylcomine on written prescription.

Don't take tomatoes, and citrus fruits.
Avoid onion, garlic, excessive tea and coffee, chocolates,
Avoid oily and spicy food, non veg.
Take soft diet along with yogurt.

Hope that helps.
Let me know your other query.
Take care,
Dr. Mayank Bhargava
